The line spectra of atoms provides experimental evidence for
A)the organization of particles in the nucleus of atoms.
B)the number of protons.
C)the arrangement of electrons.
D)all of the above

Question

Quizplus · Accepted Answer

The line spectra of atoms result from the transitions of electrons between energy levels. The arrangement of electrons in their respective energy levels determines the wavelengths of the emitted light, which produces unique spectral lines for each element. Therefore, the line spectra provide evidence for the arrangement of electrons in atoms. The organization of particles in the nucleus of atoms and the number of protons in the nucleus can be determined by other experimental techniques such as X-ray diffraction and mass spectrometry, respectively.
